What a load of shit. If laquer is looked after properly, it will last just as long as 2K. I've seen laquer look just as good as the day it got sprayed, 23 years after the fact.
Also, this is laquer WITHOUT clear
Sure if you have a bit of money to spend, the skills to spray and a temperature controlled spray booth to use, go 2K, but IMO, if you're going to paint your first car, in a shed, using basic equipment, then use laquer. It's cheap, forgiving and doesn't have as many asociated health risks.
